Have information for 7 generations of the Nichols that settled into Lowell in the mid-1800's. Also, working to establish family connections with the Pinkertons through James and Sarah (Sanders) who moved back into Lowell. Trying to find the family line that leads up to James Pinkerton. His parents are Francis and Ellen (Anderson). I have her parentage traced back through the Sanders and Morses pre-1790.I'm especially interested in any ties with Allen Pinkerton of the Pinkerton Detective Agency.
